Abstract

In this chapter, we deal with a simple but realistic optimization problem. We have to find the optimal temperature in an industrial furnace, used to form resin pieces, such as car bumpers. The heating system is based on electric resistances, and the first part of this study is to compute the temperature field inside the oven when the values of the resistances are known. This step is called the direct problem: the resistances’ values are known and the temperature field is unknown. The second part of the study is devoted to computing the resistances’ values in order to maintain the bumper temperature at a prescribed value. This optimization problem is called an inverse problem: the temperature is the input and the resistances values are the outputs. For the numerical implementation, we use 2D triangular finite elements.
